Patent DE-3145339-A1 (DE)
Title: Spark plug with ignition chamber
Inventor: LINDER ERNST DIPL ING
IPC: H01T13/39
Filed: 1981-11-14
Abstract: The spark plug (2) is intended for a reciprocating piston internal combustion engine and has an ignition chamber (14) in which two electrodes (4, 5) which form an ignition spark gap (17) between them are arranged. One of the electrodes (4) is of tubular construction and during compression strokes of the internal combustion engine inflammable fuel/air mixture flows around and through said electrode. This electrode (4) is of thin-walled construction in such a way that after it has been previously warmed up by fuel/air mixture ignited in the combustion chamber, during the next intake stroke and during the following compression stroke it cools down very rapidly below that temperature which could trigger self-ignitions as a result of fresh fuel/air mixture flowing into the ignition chamber. <IMAGE>
Patent DE-3150434-A1 (DE)
Title: Break-off screw
Inventor: FISCHER ERICH
IPC: F16B41/00
Filed: 1981-12-19
Abstract: The novel break-off screw (Figure 1) is intended for the secure fastening, in particular of such parts which, like, for example window grilles, serve to prevent break-in. The break-off screw (10) has a metal or wooden threaded shank (11) and a first screw cap (12) adjoining this. Said screw cap has exclusively smooth outer surfaces, i.e. it has no portions which project forwards or backwards, depressions, etc. It is arranged on the workpiece such that it is countersunk. An intermediate shank (14) is connected integrally to said first screw cap (12) and a second screw cap (13) is connected integrally to said shank. The second screw cap (13) is provided with abutment surfaces for tools. The intermediate shank (14) has, at least in one cross-sectional plane, a smaller diameter (D), to be precise a diameter which is smaller by between 10% and 30%, than the threaded shank (11). This cross-sectional reduction forms a predetermined breaking point at which, after the threaded shank (11) with the first screw cap (12) has been tightened, the intermediate shank (14) and the second screw cap (13) can be twisted off. Owing to its lack of abutment surfaces, the countersunk, first screw cap (12) can then no longer be released. <IMAGE>

Title: Device for liquid cooling of electrical machines
Inventor: RAUSCH HARTMUTH DR ING
IPC: H02K9/19
Filed: 1981-12-22
Abstract: According to Fig. 1, the rotor of a squirrel-cage motor has a divided annular channel (15) in each short-circuit ring (13) and two pipelines (17) which are laid in the laminate stack (16). Annular elements (18) which are pushed under the short-circuit rings (13) and are themselves fitted with a divided annular channel (19) undertake the connection of the channels (15, 17, 21 and 28) in the correct sense. The fan body (5) contains a channel system (20) which is like a round thread and is connected to the shaft bore (21) and, via an annular cavity (27) and a divided annular channel (24) to the shaft bore (28). A stationary disc (29) with recesses (30) like an impeller projects and is supported in front of the channel (24) and is integrated into the fan body (5) via a sliding packing ring cassette (34) and a supporting bearing (31). The disc (29) is connected to the machine housing in a torsionally stiff manner, but decoupled with respect to vibration, via the fan dome structure (6 and 7). The invention can be used particularly effectively in the case of encapsulated electrical machines. The rotor heat loss passes via the fluid, with simultaneous thermal stress-relief of the stator, through the pumping device (24, 29 and 30) to the fan body (5), which consists of aluminium, in order to be dissipated from the surface of the latter via the fan fins (3) to the powerful airflow between the fins. Similar conditions can be achieved as for force-ventilated machines. <IMAGE>
Patent DE-3202401-A1 (DE)
Title: Agricultural implement
Inventor: THOMA ADOLF
IPC: A01B1/06
Filed: 1982-01-26
Abstract: The agricultural implement has a trapezoidal loop, the broader bottom section of which is formed by a wire-like bow and the shorter upper section of which is formed by a connecting piece connecting the ends of the bow, to which connecting piece a shaft can be fixed. The bow end sections at least partially form the side arms of the trapezoidal loop. As a result, not only can a wide tract of ground be worked but, by turning the shaft about its longitudinal axis, the loop can be brought broadside so that the narrow side of the trapezium, with a point in front, can easily be drawn through the earth in order to extract even deep-seated roots. The implement can also be used for breaking up the soil. It is especially suitable for softer garden soil, for example in allotments and on strawberry fields.

Title: Tobacco purifying process
Inventor: BORBE DIETER
IPC: A24B15/24
Filed: 1982-05-03
Abstract: The tobacco purifying process serves for treating tobacco products intended for human consumption, in order to reduce their content of nicotine, condensates such as hydrocarbons, and other harmful materials injurious to the organism. For this purpose, a charge of the tobacco product is placed into a water bath and treated with water therein, the time of the water treatment being all the longer, the lower the bath temperature. After the water treatment has been carried out, the tobacco charge is freed of the water bath loaded with dissolved or suspended harmful substances, and the excess water together with further harmful substances is removed from the tobacco charge by applying pressure. Finally, the pre-drained tobacco charge is subjected to a drying process. For this purpose, the tobacco charge can be spread out on a drying surface or introduced into a drying vessel and thus subjected to air drying.

Title: Hydro-pneumatic percussion device
Inventor: JANZEN IVAN A
IPC: E02D3/046
Filed: 1982-06-04
Abstract: The percussion device is intended for use in various branches of construction such as, for example, compaction of soils in confined conditions, destruction of concrete and bitumen-concrete pavements, stone blocks, loosening of solid and hard-frozen earth. The percussion device is provided with a casing (1), in the inner space of which a housing (2) with radial passages (32, 35, 36, 42, 45, 48) is accommodated while being enabled to move in a reciprocating manner. Mounted in the casing (1) is a working tool (23), the shank (22) of which is guided into the stroke volume of the housing (2). Accommodated in the stroke volume of the housing (2) of stepped configuration is a percussion piston (11), likewise of stepped shape and having sections of larger diameter (14) and smaller diameter (12, 13), which forms with the housing (2) three stroke volumes (18, 19, 20). The stroke volume (18) is used for filling with pressure gas and here appears as a pressure-gas accumulator. The stroke volume (19) communicates with the hydraulic discharge line (33) via the passage (32). The stroke volume (20) is connected by the radial passages (35, 36) to the hydraulic pressure line (34). The intermediate distance between the radial passages (32 and 35) in the housing (2), which are connected to the hydraulic pressure and discharge line (4' and 5'), can be divided by the maximum intermediate distance between the working tool (23) and the percussion piston (11). A stem (21) movable in the axial direction is accommodated coaxially to the working tool (23) in the housing (2), one end projecting into the stroke volume (18) and the other end interacting with the casing (1) to transmit a force to the casing (1) from the pressure-gas accumulator. In order to bring about its automatic mode of operation, the percussion device is equipped with a hydraulic distributor (7) which has accommodated in the cylindrical inner space (38) of its housing (37) a slide (46) which separates this cylindrical inner space into two sections (40 and 41). One section (40) of the cylindrical inner space is constantly connected to the stroke volume (19) by a radial passage (45) of the housing (2). The other section (41) of the cylindrical inner space of the hydraulic distributor (7) communicates via a radial passage (48) with an annular recess (15) on the percussion piston (11). Made in the circumferential surface of the hydraulic distributor is a bore (39) which is covered in alternating manner by the slide (46) and is connected via the radial passage (42) in the housing (2) to the stroke volume (20) communicating with the hydraulic pressure line (34). <IMAGE>

Title: Device for altering the intake cross-section in a piston-controlled two-stroke internal combustion engine
Inventor: LIEBERT HEINZ
IPC: F02D13/02
Filed: 1982-09-03
Abstract: Device for altering the intake cross-section and the change with time of the opening time of the intake port in a piston-controlled two-stroke internal combustion engine. The invention relates to a device for altering the intake cross-section and to the change with time of the intake, which is achieved by lowering or raising the bottom edge of the intake, in order to be able to better utilise the fuel drawn in and to reduce the excess of fuel with a constant time or a constant intake cross-section, which occurs in various speed ranges. This object is achieved by virtue of the fact that the bottom edge of the intake is raised or lowered by means of a pivotable plate via a linkage, the drive of which is a centrifugal clutch or a computer-controlled driving part (Fig. 1 A and travel X), and this has the result that the opening time of the intake is lengthened or shortened and the cross-section enlarged or reduced. By virtue of the invention, the fuel/air mixture drawn in is burnt by the engine without leaving unburnt fuel/air mixture to be expelled. The invention is mounted in the intake port by means of two bushes. A stuffing box seals off the cylinder casing where the removable shaft journal enters the casing with the reversing lever. <IMAGE>

Title: Device for ventilating buildings
Inventor: DREHER WOLFGANG DIPL ING
IPC: E04F17/04
Filed: 1982-10-16
Abstract: The device for ventilating buildings comprises a housing which can be mounted on a horizontal or sloping roof surface of a building over a foul-air opening, bounds, with outer longitudinal and transverse walls, a foul-air shaft and is provided with fittings. These fittings pass through the foul-air shaft transversely to its longitudinal direction, impart a plurality of deviations to the flow of the foul-air and cover the foul-air opening in its entirety for weather protection thereof. To improve the efficiency, the fittings are grouped in this case into a plurality of layers, approximately parallel to one another and to the plane of the foul-air opening and arranged freely at a distance one above the other, and in each layer the fittings assigned to this layer define a number of passage openings for the foul-air, which are arranged in an approximately common plane at a distance next to one another. In the weather position of the device, the passage openings in the layers are in this case arranged so as to be offset, from one layer to another, relative to one another in the longitudinal direction of the foul-air shaft.

Title: Supercritical steam-power machine cyclic process
Inventor: GENSWEIN ALFONS DIPL ING
IPC: F01K7/32
Filed: 1982-11-11
Abstract: The invention describes a supercritical steam-powered machine cyclic process (for steam turbines and/or piston steam machines), in which a hot or cold gas which is used as the operating material, is obtained from the fluid state in the supercritical state region (P>/=Pk,t = tk), and is further superheated (t>tk) at a constant supercritical pressure (Pk1 = constant, Pk1 > Pk) is brought to the expansion limit point of an (any desired) expansion machine for complete condensation, the condensate obtained (with the minimum possible flow volume and without external emission of heat) being inserted into the cyclic process again with the minimum possible operating cost. All the fluid and superheating heat (qf+qu = qzu) absorbed from the exterior by the cyclic process can be converted into work and can be emitted to the exterior in a useful manner (Wab = qzu). Application especially for stationary hot-steam and cold-steam power stations (steam power stations). Opportunities and advantages in the use of high-quality energy carriers (fossil and/or nuclear fuels) and of lower-quality energy carriers (thermally balanced water and/or air flows) are indicated. <IMAGE>

Title: Sweeping shovel
Inventor: SCHWEBEL ERNST DIPL ING
IPC: A47L13/52
Filed: 1983-02-25
Abstract: In sweeping shovels of any kind, there is the problem of the fastening or of the transition of the basic shovel body to the handle. Irrespective of whether the basic shovel body and the handle are made in one piece or whether the handle is fastened to the basic shovel body, this is generally the weakest point of such sweeping shovels, at which damage, such as a breaking off of the handle or the like, occurs first. Especially where plastic shovels are concerned, under load the sidewalls can fall in and the rear wall bend out. What is proposed is a sweeping shovel with a possibility of stable fastening of the handle to the basic shovel body, which imparts increased stability per se to the basic shovel body by providing a U-shaped clamp made of bend-resistant material, of which the side legs bear with a clamping effect against the sidewalls and the web against the rear wall of the basic shovel body, the handle either being part of the U-shaped clamp or else being fastened separately to the basic shovel body.
